Inspection of tall containers such as Number Ten gallon cans must reflect consideration of two important X-ray inspection principles:

• Package dimensions: to identify foreign material in a large container, you should contrast it with as little of the standard material as possible. So, inspect through a container at its narrowest dimension. For rigid packages whose height is typically greater than their diameter, inspect from the side, through the diameter
• X-rays and distance: X-ray strength decreases inversely with the square of the distance traveled. For tall containers, the X-ray strength will decrease materially from the bottom of the container to the top because the distance the beam travels increases substantially

These principles influence the inspection resolution and the inspection quality that can be expected from X-rays and the particular system making the inspection.
